eek...
i also hang my bag around my neck while in a public restroom or am doing my business akwardly while still squeezing it to my side/on my shoulder! as far as the neck thing goes...just literally act like your heck is a hook to hang your bag from...if you normally carry bags that go on your shoulder...it will go around your head like a necklace!
I always drive with my purse on the center console or my lap. It goes no where else!!!!
This is something that bothers the heck out of me. It can be a pain to comfortably use a public restroom, and I'm not willing to do what I see a lot of other women doing, which is to put the bag on the floor. First, yuck. Second, it could get stolen. The hook that is usually on the inside of the stall is too high up, so a tall thief can just grab the bag off the hook, and it's not like you're in a position to chase them! A small shelf that folds down would be nice, or a larger hook that isn't accessible by reaching over or under the stall.
